This is a "starting from scratch" question. I do not know how to enable the zenpage plugin. My theme is set to Effervescence+, my custom page is set to gallery but zenpage does not come up in the list of plugins. I have searched this forum but it seems as though everyone is much more advanced than me because I don't see it referenced, unless I am not searching correctly. Any help is appreciated.

You have to enable the plugin on the plugins page on the admin backend.

It is not on the plugins page on the admin backend.

I just checked in file manager and there is no folder for zen page in the zp-core/plugins folder. That explains it so where do I get the plugin and how do I install it?

The plugin is in the standard download, so click download from at the top navbar on this site, grab your archive of choice, unzip it, and upload it. You may want to upload the entire archive though because if you're missing that folder there's chances that you're missing other things as well.

OK, thanks, I'll give it a try. I have version 1.2.1 but with me anything can go awry. Once again, thank you for your time.

Well, the current version is 1.2.6 and 1.2.7 is soon to be released, so you will need to upgrade.
